We have an AVID ISIS 7500 server (which is End of Life) with a total of 5 engines (5 chassis). We have a total of 80 blades. 

Since we are End of Life - we are looking for scale down the server space from 5 Engines to 4 total engines. We are looking to use the Extra Blades as spare parts (Currently have a network degreaded error on one of the blades)

My understanding is that I can remove one of the Engines in Switch Blade Management Console (Switch Blade Page) - under System - Add/Remove Chassis. 

My question is if I should remove each individual Blade in this chassis first to re distribute the Data across the other engines? 

So remove all 16 ISB on that Engine? 

Or would simply removing the Chassis from the group redistribute the data without loss?

We have enough data storage left to do this (58 TB Used || 239 TB Unused || 182 TB Allocated || 114 TB Unallocated). 

Thank you !

You need to have your allocated space to be less than 4 chassis worth. You can then remove the 5th chassis. This will trigger a redistribution. Once it is done, you can unbind the chassis. Shut it down and reserve for spare parts.

Great !!Thank you for the fast response. I will reallocate space on our workspaces to go below 128 TB and try this after the end of our semester. Thanks again

Hi,

Make sure after you power down the chassis and those isb's that they power up when you apply power again.

ISIS 7x00 weakest point was power regulation chips on the storage blades and switch blades that die after a few years of use. So when done make sure they still work before storing them on a shelf. Nothing worse then thinking you have spare parts and discovering they don't work when needed.

Thank you for the suggestion. I will do that. 

I assume once the Optical and Ethernet connections have been removed - I shouid be able to power up the Chassis without disrupting the system? 

Thank you!

Help with AVID ISIS - Connection (No connection from Client Machine - or access to Admin Console)

I was attempting to downscale our AVID ISIS 7500 from a 5 engines to 4 engines. 

I removed all the ISBs from Engine 3 (which we are taking offline to use for spare parts) - the redistribution successfully finished overnight. I then unbound the ISBs from the engine. 

Attempted to Remove the Engine by logging into the Engine - and this is where something went wrong. 

I first had intermittent connection issues using the Client Manager and the Admin Console from my client machine. 

The System Director - however - does not show any specific issues and I am able to see all the engines and ISB (in AVID Monitoring Tool). I can also see the Admin Console on the System Director and Log in to the Engines. 

I am seeing a possible issue with the Global Stack table - since the Add/Remove engines is not visible - and gives me a “No entries found in the Global Stack Table”

In addition - the Engine I tried removing shows me a “State: SW_PORT_DELETED_STATE

Is there a possoible IP issue from Client machine or anything I should look for. 

The system director does not show any errors currently

Any help or advice would be highly appreciated. 

Thank you
